I came across the following code:
const { userinfo } = userInfo;
I'm wondering, why do we use curly brackets with the const here?

In Javascript this syntax is called destructuring assignment and more specifically object destructing. Let's say you have an object:
const obj = { data: {...}, user: {...} }
For instance, when you write:
const { data, user } = obj
console.log(data)
Here you define new variables data and user and assign corresponding property values from the object obj to those variables.
It seems like in your case you have a local variable:
userInfo = {userInfo: {...} }
const { userinfo } = userInfo;
Deconstructing userInfo into { userInfo } would give you an error:
Uncaught SyntaxError: Identifier 'userInfo' has already been declared
